Last time we were at Otter Lake was about three years ago. A very nice campground. There were daily activities, which included, archery, baseball, ceramics (you paid for the item to paint), bingo, a movie every few nights, and I am sure I am missing something. There
was an outdoor pool and an indoor spa/pool/or something like that. There was also a lake, with a beach, and I saw people fishing in the lake. I believe hiking trails were also in the campground.
Otter Lake had a nice general store that sold ice cream.
One word of caution-Otter Lake is not really close to anything in the area, so bring enough supplies for the week.
